I have made some changes in a designer layout and i have this error when i try to compile.
The appli work fine before...
I don't understand what is the problem. Any Idea ?

Thank's by advance for your help

Hi,

to check - have you added any new or renamed controls to the B4J code?
An error message like

Object should first be initialized (AnchorPane)

is typically a sign that a control declaration is missing.

Thank's Rob,

I delete the anchorPanel from the layout but the control is already declared in the globlals as
"Private admin_panel As AnchorPane"

As soon as i recreate this control, all is ok.

Sorry for my poor english
